Problems solved by technology
Conversely, a cross of two plants each heterozygous at a number of loci produces a population of hybrid plants that differ genetically and are not uniform.
The resulting non-uniformity makes performance unpredictable.

Embodiment Construction
[0041]The invention provides carrot plants and in particular carrot cultivars or lines having increased lycopene content. Such carrots can be referred to as high lycopene carrot varieties. In a certain aspects, the carrot plants are hybrid carrot plants. Also disclosed herein are carrot cultivars or lines having increased lycopene content and cytoplasmic male sterility. Methods of breeding high lycopene carrot lines are also provided. Also disclosed herein are F1 hybrids of the high lycopene carrots.
[0042]As part of this invention, long, cylindrical shaped carrots containing the carotenoid lycopene have been developed to fit market needs, including the processing needs for the cut and peel market segment. Lycopene has received much attention with regard to its anti-oxidant capability in warding off cancer development, particularly in the digestive tract. In some embodiments, the carrots provided by this invention can be used to produce a solid red colored pack of cut and peel produc...

The present invention relates to carrot lines having roots containing increased levels of lycopene, as well as containers of such carrots. The present invention also relates to parts of carrot plants from lines having roots with increased lycopene content, including seeds capable of growing carrot plants with increased root lycopene content. The invention also provides seed and plants of the carrot lines designated RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B. The invention thus relates to the plants, seeds and tissue cultures of carrot line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B, and to methods for producing a carrot plant produced by crossing a plant of carrot line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B with itself or with another carrot plant, such as a plant of another line. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of a plant of carrot line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B, including the fruit and gametes of such plants.
Description
[0001]This application claims the priority of U.S. provisional application Ser. No. 60 / 852,397, filed Oct. 18, 2006, and U.S. provisional application Ser. No. 60 / 905,809, filed Mar. 9, 2007, each of the disclosures of which are specifically incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]A. Field of the Invention[0003]The invention relates to the field of plant genetics and, more specifically, to the development of carrot plants having increased lycopene content.[0004]B. Description of Related Art[0005]Carrot (Daucus carota var sativus), a member of the Umbelliferae family, is one of the most important root crops and is grown on over 100,000 hectares worldwide. Carrots provide an excellent source of various vitamins and minerals, including vitamin A (beta-carotene), as well as dietary fiber content in animal diets. Breeding efforts over the last half century have resulted in a 75% increase in the beta-carotene content in cultivated carrots. Recently, interest in th...
